These operators are used in a program to assign a value of the right-hand side to the left-hand side as shown below.
1 2 3 4 5 6 7 | //10 is assign to the variable a int a = 5; //the value of b (10) is assigned to a int b = 10; int a = b; int a += 2; //a=a+2 |
You can combine write in short version such as instead of writing, int a = a+5, you can write it as a += 5.
Following are the list of assignment operators used in C#.
| Operator | Description |
|---|---|
| = | Simple assignment operator, Assigns values from right side operands to left side operand.a = b + c; |
| += | Add AND assignment operator, It adds the right operand to the left operand and assigns the result to the left operand.a += b |
| -= | Subtract AND assignment operator, It subtracts the right operand from the left operand and assigns the result to the left operand.a -= b |
| *= | Multiply AND assignment operator, It multiplies the right operand with the left operand and assigns the result to the left operand.a *= b |
| /= | Divide AND assignment operator, It divides left operand with the right operand and assigns the result to the left operand.a /= b |
| %= | Modulus AND assignment operator, It takes modulus using two operands and assigns the result to the left operand.a %= b |
| <<= | Left shift AND assignment operator.a <<= 2 |
| >>= | Right shift AND assignment operator.a >>= 2 or a = a >> 2 |
| &= | Bitwise AND assignment operator.a &= 2 or a = a & 2 |
| ^= | Bitwise exclusive OR and assignment operator.a ^= 2 or a = a ^ 2 |
| |= | Bitwise inclusive OR and assignment operator.a |= 2 or a = a | 2 |
Example of C# Assignment Operators
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 | using System; namespace Operators { class Assignment { static void Main(string[] args) { int a = 11; int result; result = a; Console.WriteLine("'+' operator, Result: {0}", result); result += a; Console.WriteLine("'+' operator, Result: {0}", result); result -= a; Console.WriteLine("'+' operator, Result: {0}", result); result *= a; Console.WriteLine("'+' operator, Result: {0}", result); result /= a; Console.WriteLine("'+' operator, Result: {0}", result); result = 200; result %= a; Console.WriteLine("'+' operator, Result: {0}", result); result <<= 2; Console.WriteLine("'+' operator, Result: {0}", result); result >>= 2; Console.WriteLine("'+' operator, Result: {0}", result); result &= 2; Console.WriteLine("'+' operator, Result: {0}", result); result ^= 2; Console.WriteLine("'+' operator, Result: {0}", result); result |= 2; Console.WriteLine("'+' operator, Result: {0}", result); } } } |
Output:
1 2 3 4 5 6 7 8 9 10 11 | '+' operator, Result: 11 '+' operator, Result: 22 '+' operator, Result: 11 '+' operator, Result: 121 '+' operator, Result: 11 '+' operator, Result: 2 '+' operator, Result: 8 '+' operator, Result: 2 '+' operator, Result: 2 '+' operator, Result: 0 '+' operator, Result: 2 |
